IIS is writing these log files. &nbsp;Look for you Default Web Site in IIS Manager, and you will find 'log visits' in its properties.

<div>
Aha! &nbsp;you are correct. &nbsp;what is the recommended setting for these types of log? &nbsp;it is currently set for daily. &nbsp;What is the main reason its on?
</div>


<div>
You can set it to whatever you like. &nbsp;The logs are only there to show you who's been using your web site. &nbsp;If you're not likely to need to check, then you can just turn it off.
</div>


<div>
so if i delete these files it would be deleting the log files of who has logged into my WebMail for that particular day?
</div>


<div>
By the way - you can double-click one and it will open in Notepad. &nbsp;This will give you some idea of what's in them.

<div>
thanks bud. &nbsp;your a Genius. &nbsp;
